SASH -CQRD GUIDE.

SPECIFICATION forming part of Iletters Patent No. 395,238, dated December 25, 1888.

Application filed April 14, 1888. Serial No. 270,624. (No model.)

To aZZ whom it may concern.-

Be it known that I, W'ARREN T. KELLOGG, ol' the village of Lansingburg, county of Reusselaer and State of New York, have invented a new and useful Improvement in Sash-Pulleys, of which the following is a specification.

My invention relates to improvements upon that class of sash-pulleys which have cases or boxes which are adapted to be inserted in a windo\vi'ra1ne by means of a socket produced therein by boring a series of intersecting auger-holes that give to the socket rounded ends and upon the sides rounded-out swells made where the al'iger-holes intersect each other.

As heretofore produced this class of sasheord guides have been made to have rounded out swells or vertically-arranged ribs upon their sides from end to end, so as to closely fit into the intersecting auger-holes forming the socket bored to receive them. As thus constructed, when driven into the socket, the sash pulley or guide had a tendency to split the wood thereat. To remedy this difficulty occurring in these older form of cases is the object and purpose of my invention, and this I accomplish by employing the same form of sec! at before used, but changing the form of the sides of the body of the case or guide, so as to have vertically-arranged ribs or roundedout swells or projections upon the sides of the case, in combination with vertically-arranged fiat portions of the case upon the sides thereof, said fiat portions being arranged thereon between said vertical rounded-out swells or ribs 01' the case and the rounded ends, so that when the sash-cord guide or case is inserted in the socket the flat portions of the sides, where adjoining the ends, will not be in contact with the wood to wedge and split the same when driven into place.

Accompanying this SDOClfiCtllOll to form a part of it there is a plate of drawings containing five figures illustratinmy invention, with the same designation of parts by letterrefercnce used in all of them.

Of the illustrations, Figure l, is a perspective of my improved sash-pulley case. Fig. 2 is a top view of the same with pulley inserted therein. Fig. 3 is a side elevation thereof.

Fig. 4 a transverse section taken on the line a .r of Fig. 3, and Fig. 5 is a view of the socket bored to receive the case.

The several parts of the device thus illustrated are designated by letter-reference, and the function of the parts is described as follows:

The letter P designates the pulley that is perimetrally grooved to receive the sash-cord.

S indicates the pulley-shaft having its bearings in the case 0. r

The letters R designate swells made in the sides of the case, which swells where diametrically opposite form parts of the same circles.

The letters F designate flat surfaces upon the sides of the case at the rounded ends, and E the latter.

The letters L designate flanges made at the ends on the edge of the case-face to overlap the flat side parts, F, and the letters designate tapering wedge-form blades arranged on the flat surfaces F on the side swells, R, and on the rounded ends E.

The pulley and case thus constructed is attached to the window-sash in the following manner: Four auger-holes are bored to intersect each other, as shown at Fig, 5, with the cross-diameter of these holes equal to the cross-diameter of the case taken through the swells R from side to side and intersecting each other, so that the distance from the rounded ends measured longitudinally shall be equal to that of the ease measured from end to end. The case is then driven. into the socket thus provided and secured by nails driven into the wood through the recesses r in the ends of the case. hen thus inserted, the pulley-case is firmly held in the sides and ends of the socket with the sides of the case at the ends free from the wood, thus preventing any wedging tendency to split the sashframe thereat.

Considered alone and by themselves, the side swells, R, are not new; neither are the blades \V when considered by themselves or in connection with said side swells.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
